The North American Aerospace Defense Command (NORAD) revealed on Tuesday that U.S. fighter jets intercepted six Russian warplanes off the coast of Alaska on Monday.

The four bombers and two fighter planes were intercepted by F-22 jets after they entered an area known as the Alaskan Air Defense Identification Zone, NBC News reports. In a statement, NORAD said the Russian planes "remained in international airspace and at no time did the aircraft enter United States or Canadian sovereign airspace," and the U.S. jets kept an eye on the Russian planes until they left the region.

Russia's Ministry of Defense said the planes were conducting planned exercises, which took place "over the neutral waters of the Chukotka, Bering, and Okhotsk Seas, as well as along the western coast of Alaska and the northern coast of the Aleutian Islands." Catherine Garcia

Discussions are now underway for the meeting, to take place during celebrations on Nov. 11 marking the 100th anniversary of the end of World War I. Putin and Trump last met in Helsinki in July.

Bolton is in Moscow to discuss the U.S. soon withdrawing from the Intermediate-Range Nuclear Forces (INF) treaty. Russia has called the step "dangerous," and per a transcript provided by the Kremlin, Putin said to Bolton, "As I recall, there is a bald eagle pictured on the U.S. coat of arms. It holds 13 arrows in one talon and an olive branch in the other. My question: Has your eagle already eaten all the olives, leaving only the arrows?"

"I didn't bring any olives," Bolton responded. Putin and Bolton met for 90 minutes, and Bolton said he also brought up "objectionable" election meddling, and why it "was particularly harmful for Russian-American relations without producing anything in return." Catherine Garcia

The sanctions primarily target Russian oil and gas projects with companies based in the United States and a handful of other countries, and they will be difficult for President Trump to lift because he will need approval from Congress. The bill now heads to the Senate for a vote, and could be sent to Trump to sign into law before August, when Congress begins its recess.

Russian President Vladimir Putin has said the sanctions would be "harmful" to U.S.-Russian relations. The package also includes sanctions against Iran and North Korea, due to their weapons programs. Catherine Garcia
